Difference between the measured pressure value at a given location and the mean pressure value, sometimes given at the parallel of the latitude for a given location.
Industry:Weather
Devices for removing particulates from pollutant-laden gas streams. The most common type, an electrostatic precipitator, functions by charging the dust to be removed with ions and then collecting the ionized particulates onto a special surface. The collector surface is cleaned by mechanical means.
Industry:Weather
Determination of the upper-level wind by the tracking of a free balloon by electronic means other than radar.
Industry:Weather
Detection and interpretation of echoes from precipitation. Such observations are used for analysis and forecasting of precipitation, for research in cloud and precipitation physics, and for prediction of and research on severe storms. Observations may be reported in a standard format as a radar coded message. See radar meteorology.
Industry:Weather
Descriptive of snow that is in a condition to discharge meltwater. Ripe snow usually has a coarse crystalline structure, a snow density near 0. 5 kg m<sup>−3</sup>, and a temperature near 0°C.
Industry:Weather
Descriptive of clouds of extensive horizontal development, as contrasted to the vertically developed cumuliform types. See stratus, altostratus, cirrostratus, nimbostratus, stratocumulus.
Industry:Weather
Departure from symmetry. In statistics, the coefficient of skewness γ<sub>1</sub> of a random variable or of a probability distribution is defined as γ<sub>1</sub> = μ<sub>3</sub>/σ<sup>3</sup>, where μ<sub>3</sub> is the third moment about the mean and σ is the standard deviation. Where γ<sub>1</sub> > 0 the typical curve trails off toward the right and hence is said to be skewed to the right; when γ<sub>1</sub> < 0 the longer tail is on the left, and the curve is said to be skewed to the left.
